Patented Dec. 25, 1906.

Application filed December 26,1905. Serial No. 293.186.

To all whom it may concern:

Be it known that I, GEORGE D. OLAPP, of Boston, county of Suffolk, Stateof-Massachusetts, have invented an Improvement in Controlling Devicesfor Spring-Supported Vehicle-Bodies, of -which the followingdescription, in connection with the accompanying drawings, is aspecification, like characters on ,the drawings representing like parts.

WVhen driving an automobile over a rough road, the shock or jar which isgiven to its spring-supported body by the inequality of the road isseverely felt by the rider and is very objectionable, and in case theautomobile is heavy and is driven at a high speed this objection isaugmented, and, furtherm0re,'there is danger of an accident happeningfrom this cause alone.

This invention has for its object to provlde improved means forcontrolling the.

movement or vibration of the spring-supported body relative to therunning-gear, whereby the above-noted objection is overcome Theinvention consists,-essentially, ina controlling device for controllingthe vibra tion or movement of the spring-supported body relative to therumiing-gear, consisting, essentially, of the yielding members uch, forinstance, as a block of rubber, circularly or otherwise formedandmeansas, for

instance, a flexible strapfor connecting it with the body, and meansas,for instance, a flexible strapconnecting it with therun- Ding-gear.

-Figure 1 shows in side elevation a suflicient portion of an automobileto illustrate my invention provided with means embodied 1n 'my inventionfor controlling the'movement or vibration of its spring-supported bodyrelative to its running-gear. Fig. 2 is an enlarged front elevation ofthe controlling device, and Fig. 3 is a side elevation of thecontrolling device.

0. represents the axletree, or it may be one of the axles, and b thebody of the vehicle,

and 0 one of the spr ngs which support-the body. The controlling deviceembodiedin my invention is interposed between the body" and axle oraxletree or some other station-' arily-supported part of therunning-gear, bemg spectively, The controlling device comprises a y1 eding member d, which -is herein shown as a circufimeans the yieldingblock said body will attached at its upper and lower ends, reato said.body and runningear.

larly-formed 1- block, of rubberihaving a central hole dp through it.This yielding block will bel m ade quite large and a groove will beformed in its periphery of any suitable di-- mensions.

-A strap 6 passes through the hole (Z in the block d and also around abare, which is secured to the body I), said strap having a buckle e atone end which is adapted to receive the other end of the strap. By thisi d is flexibly connected with or attached to the body. My invention,however, comprehends any other form of flexible connection betweentheyielding block andthe bod and also any other means for attaching saiflexible connection to said body and to the block. Another strap fpasses around the periphery of the yielding lock (1 and around-the axleor other stationarily-supported member a of the runninggear, which has abuckle f at'oneend which 1s adapted to engage the op osite end of thestrap. At a oint between t e yielding block d and the axe or other parta the two portions of the straps are gether-as, for instance, a ring orloop- 9 is attached to one portion of the strapfthrough which the otherportion of the strap, is free to ass. By means of the strap f theyielding blockis flexibly connected with a' stationarily-supported partof the running-gear. My invention, however, comprehends any other formof flexible connection between the yielding block and running-gear andalso any other means for attaching said flexible connection to therunning-gearand to the block.

When driving the machine over, a rough road, as the. spring-supportedbody is suddenly lifted, due to an mequality of the road,-

tions and yie ding block and its upward movement. thereby restrained ina yielding manner, and no severeshock or jar will be felt. Inractice Iprefer to employ four controllin evices for each machine.

.l lavin'g thus described my invention, what I claim as new, and desireto secure by Let- ,ters Patent,-is, 1. A controlling'device forcontrolling the l movement, of a spring-supported vehiclebody relativeto, the runningear consisting of a yielding block having a hoethroughit, a strap passing through said' hole and around a preferablydrawn to- 9s pull up on the flexible connecbar on the body, and meansfor connecting said block with the running-gear, substan: tially asdescribed.

2. A controlling device for controlling the vmovement of aspring-supported vehiclem0vement of a. spring-supported vehiclebodyrelative to the running-gear; consisting of a circularly-formed block ofrubber having a central hole through it, a str'a passing throu h saidhole and a strap passing aroun said b ock, one of said straps beingconnected with the body and the other strap being connected with therunning-gear, and a ring embracing the two portions of the strap betweenthe block and running-gear, substantially as described. v

In testimony whereof 1 have signed my name to this specification in thepresence of two-subscribing Witnesses.
